run_fem_analysis
Execute a finite element analysis with CalculiX on an existing FemAnalysis, returning maximum von Mises stress, displacement, and node count.
Instructions
Run the CalculiX solver on an existing Fem::FemAnalysis container and return summary results.
Prerequisites in the document:
- A Part-derived solid (e.g. Part::Box, PartDesign::Body) acting as the geometry.
- A Fem::AnalysisPython container created via `create_object`.
- A Fem::MaterialCommon assigned to the geometry, added to the analysis.
- A Fem::FemMeshGmsh referencing the geometry, added to the analysis (the
mesh is generated automatically when created via `create_object`).
- At least one Fem::ConstraintFixed and one Fem::ConstraintForce (or
ConstraintPressure) bound to faces of the geometry, added to the analysis.
A SolverCcxTools is auto-created if the analysis has none.
The solver runs synchronously on the FreeCAD GUI thread and blocks all
other RPC calls for its duration; do not fan out parallel requests.
Returns max von Mises stress (MPa), max/min displacement (mm), node count,
and the working directory CalculiX wrote to. On failure, returns the
prerequisite-check or solver error along with the working directory for
triage.
Args:
doc_name: Name of the FreeCAD document.
analysis_name: Name of the Fem::AnalysisPython object.
timeout: Seconds to wait for the solver (default 600).Input Schema
